THREAD HOLDER Filed March '7, 1938 INVENTOR ATTdRNEYs Patented Jan. 24, 1939 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to thread holders of the type more particularly designed for use in connection with factory sewing machines.

An object of the present invention is to provide a novel bracket of substantially right angular shape and adapted to be secured to the lower side of the top of the sewing machine and to the inner face of one of the end supports of the sewing machine and store a plurality of cones of thread, the bracket being so reinforced as to resist vibration and hold the cones steady while thread is being supplied to the machine.

-A further object is to provide a thread holder of this type which will be formed of a few strong, simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claim without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming part of this specification,

Figure 1 is a plan view of a sewing machine equipped with a thread holder constructed in accordance with the invention.

Figure 2 is a front elevation of the parts shown in Figure 1.

Figure 3 is a perspective view of the thread holder.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, I0 designates a conventional factory sewing machine to which the invention is applicable.

In carrying out the invention the thread holder comprises a bracket consisting of a horizontal member 5! and a vertical member I2 extending upwardly from one end of the horizontal member, the bracket thus being substantially right angular in contour. The horizontal member is provided at its outer end with an attaching lug 13 which is provided with an opening l4 through which a bolt l5 may be passed. The vertical member is provided at its upper end with an attaching lug I6 having an opening II through which a screw l8 may be passed. The members H and I2 and the attaching lugs I3 and I6 are provided at their edges with reinforcing and stiffening flanges [9. These flanges prevent vibration of the bracket so that the thread holder is maintained rigid to steady the cones of thread while the thread is being fed to the machine.

The horizontal member H is provided with a pair of spindles 2| to receive the cones of thread and these spindles may be rigidly secured in position in any preferred manner, preferably by welding. It will be pointed out that the formation of the bracket and the arrangement of its attaching lug is such that the bracket may be secured to the lower side of the top 22 of the sewing machine and to one end support 23 of the sewing machine.

A longitudinally'split guide tube 24 is mounted on the top 22 of the machine and the lower end thereof communicates with a slot 25 formed in the top of the machine through which slot the thread oscillates as it is being payed off from the respective cone of thread to the needle bar of the sewing machine.

A longitudinally split tube 26 is secured to the top 22 of the machine for supplying thread to the empty bobbin winding device 21 so that the thread of the needle bar need not be broken when it is desired to wind thread on the bobbin, the thread being supplied from the companion cone of thread. The lower end of the tube 26 communicates with a slot 28 through which the thread oscillates as it is being payed off from its respective cone of thread to the bobbin winding device.

From the above description it is thought that the construction and operation of the invention will be fully understood without further explanation.

What is claimed is:

A thread holder comprising a bracket formed of strap metal consisting of a horizontal member and a vertical member extending upwardly from one end of the horizontal member, an attaching lug on the outer end of the horizontal member extending downward perpendicular to the member, an attaching lug formed at the upper end of the vertical member extending outwardly perpendicular to the member, reinforcing flanges formed on the longitudinal edges of the members and attaching lugs, and spindles extending vertically from the horizontal member in the median plane of the vertical member.
